CAUTION: Before servicing
receivers covered by this service manual and
its supplements and addenda, read and follow
the SAFETY PRECAUTIONS of this publication.
Remember: Safety First.

General Guidance
An isolation Transformer should always be
used during the servicing of a receiver
whose chassis is not isolated from the AC
power line.

Use a transformer of adequate power
rating as this protects the technician from
accidents resulting in personal injury from
electrical shocks. It will also protect the
receiver and it's components from being
damaged by accidental shorts of the
circuitry that may be inadvertently
introduced during the service operation.
